Smelting process of A514 grade E alloy steel plate, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.
Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel A514 grade E alloy steel plate and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.
In order to improve the A514 grade E alloy steel plate corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main A514 grade E alloy steel plate coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking A514 grade E alloy steel plate sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
After extrusion, the A514 grade E alloy steel plate tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
